Keratoacanthoma Definition
Keratoacanthoma is a fairly common, epithelial tumor. Formerly, it was regarded as variant of Squamous Cell Carcinoma; a form of malignant cancer that occur in many different organs of the body including the skin, lips, esophagus, and mouth among other else.

It will then grow a keratin-filled ?crater?, surrounded by crust. When left untreated, tumor will continuously grow and may last for 6 weeks. Slow regression is observed from 2-12 months. Keratoacanthoma can either appear alone or in multiple. The tumor is painless but can be itchy at times.
